Application led May 1,

To all whom 'it may conce/m.'

VBe it lmownthat I, JOHN IHRIG, of Rochester, in the county of Monroe and State of New York, have lnvented certain new and useful Improvements in Cooling Devices; and I do hereby declare the following to be a full, clear, and exact description of lthe same, reference being had to the accompanying drawings, forming a part of this specification thereon. A My invention relates to cooling devices for use in cold'storage plants and similar places,

and it has for its object to provide a portable apparatus that will effectively cool a cold storage room, the parts being constructed and arranged so as to effect a very large saving in the amount of ice consumed, for any given amount of cold roduced. Thatl is to say, with my improve apparatus, it is 'possible to produce a maximum amount of cold from a minimum supply of ice.

A further purpose of my invention resides in providin in the same apparatus a freezing or refrlgerating chamber, for fowl or other small meats and the like, without increasing to any substantial extent the amount of ice that would otherwise be consumed.

Still another object of my improvement consists in aording such a construction that the diiierent parts are readily accessible for cleaning, and the supply of ice ymay be replenished as often as necessary with considerable ease.

sists in certain improvements and combinations of parts all as will be hereinafter more fully described, the novel features being" pointed out in the claims at the end of the specification.

In the drawings: Figure 1 is a side eleva- .tion of an apparatus constructed 1n accord,- ance with a preferred embodiment Vof the invention; Fig. 2 is a transverse sectlonal view; Fig. 3 is a'longitudinal sectional view, and Fig. 4 is a horizontal sectional view.

Similar reference numerals in the several figures indicate the sameparts.

c IThe invention, as illustrated in the present embodiment, preferably comprises acasr ing supportedon the frame land provided with double walls 2, which consist of inner and outer partitions that serve to retain the cold 4within the casing and to prevent en- 'i v55 trance of the hot air from the outside through the walls of the casing, all of which and to the reference-numerals marked To these and other ends the invention conf matentedliebdli. 1913. seriainmeavee. y

tends to effect a saving in the amount of ice consumption.

Within the casing there is arranged an ice chamber designated at 3,` which is disposed 1u spaced relation to the walls of the casing so Aas to afford a passage allv around for the currents of air, as will be more fully described hereafter. i

The ice chamberv 3 is intended to be filled with crushed or broken ice, as indicated at 4, and 1n order-to permit the ice chamber to be readily' filled, it is provided with a removable cover constructed vin twosections and 6 respectively, which may be connected in the manner shown in Fig. 3.

Disposed beneath the ice chamber are a serles of refrigerating or freezing compartments 7 -which are designed to receive small articles of meat and similar goods that must be kept very cold, and at or near freezing temperatures, said compartments being accessible through the doors 8, and adapted to be maintained at the desired temperatures by the means that I will now describe. To this end, a cooling coil 9 is provided which eX- tends around three sides .of thecompartment section and is connected with an ov'erliow trough gutter 10 disposed at the bottom of the ice chamber, to receive the brine and melted ice as it flows out from the ice chamber, the latter being provided with outlet pipes 1l at the bottom thereof for this purpose. rlhe lower end of the cooling coil 9 which is indicated at 12, may be connected with any suitable discharge, through which the'water is carried od' from the apparatus.

In order to induce a circulation of air about the ice chamber and between it and the walls of the casing, I provide above the ice chamber suitable air current producing means, preferably in the form of an electrically operated fan 13 which is mounted on a suitable support 14, I have found that the best results are obtained when the' fan is directed upwardly at a slight angle as shown at Fig. 3, although this arrangement may be varied without changing the essential principles of the invention, and in order to deflect and break up thecurrents produced by the fan, there yis provided an adjustable vbaiile 15, which is preferably hinged as shown, and may be held in any one of several positions by means of the movable support lf3-which is adapted to en-` gage the projections 17 on the cover of the ice chamber.- By this means, the air is thrown forcibly against the baie by which a part of it is directed upwardly, while a suicient amount passes to both sides of the baiie in a downward direction, going around the walls of the ice chamber until it is discharged at the bottom of the casing. A continuous circulation of this kind is kept up, the air in the room orcompartment in which the apparatus is placed being thus constantly cooled and freshened. Owing to the arrangement of the ice chamber in spaced relation to the walls of the casing, in connection with the means for influcing acurrent of air continuously in a downward direction about the casing, I am able to maintain the air in the room at a sufficiently low temperature for the pur'- poses required, with a comparatively small expenditure of ice.

It is desirable that none of-y the air be forced in a direction laterally of vthe apparatus into the room, lest it may strike di- -rectly upon.- some of the meats or other goods, and to this end there is preferably providedahood 18 at the top of the casing, which extends entirely around the apparatus and is high enough to inclose the fan 13, as shown in Fig. 3, so that any forced currents of air that are induced by the fan, move either downwardly through the apparatus or in a direction upwardly through the hood, being discharged at the top or bottom.

I claim as my invention:

1. A cooling apparatus comprising a cas ing open at the bottom, a closed ice chamber arranged within the casing in spaced relation tothe walls thereof, a refrigerating compartment arrangedl beneath the ice chamber, a cooling coil surrounding the refrigerating compartment and communicating with the ice chamber, and air circulating means disposed above the ice chamber and acting to direct currents of air downwardly between the walls of the chamber and casing and discharge it at the bottom of the casing.

2. A cooling apparatus comprising a casing open at the bottom, a closed ice chamber arranged within the casing in spaced relation to the walls thereof, a refrigerating compartment disposed beneath the ice chamber, an overiow gutter surrounding the bottom of the ice chamber, anda cooling coil JOHN IHRiG.
